The Scupham Sonnet is noted at Vol Central as not a “proper” sonnet, probably because of the lack of prescribed pivot. It was created by British poet Peter Scupham and uses the Scupham Stanza.The Scupham Sonnet is:

a quatorzain made up of 2 Schupham stanzas (sixains) followed by a rhymed couplet.

metered, iambic pentameter.

rhymed, scheme abccba deffed gg.

no prescribed place for a pivot but most good poetry naturally has a pivot or turn someplace within the poem.

The Scupham Stanza is a sixain used in the Scupham Sonnet but which could be stand-alone poem or written in any number. It was created by British poet, Peter Scupham and is found at Vol Central.The Scupham stanza is:

stanzaic, written in any number of sixains.

metered or not at the discretion of the poet. (When using it in a sonnet, in deference to the form, iambic pentameter would be my choice.)

Peter Scupham likes abccba stanzas. Two of these plus a rhyming couplet make something very like a sonnet. This is not a “proper” sonnet, strictly speaking, but I think of it as a Scupham Sonnet. (This is not a standard name).
